The missing coefficient of the x-term after finding the product of (-x - 5)², is: C. 10.

<h3>What is the Coefficient of a Variable?</h3>

The coefficient of a variable is the numerical value that comes before the variable and multiplies it.

Find the product of (-x - 5)²:

(-x - 5)(-x - 5)

-x(-x - 5) -5(-x - 5)

x² + 5x + 5x + 25

x² + 10x + 25

The x-term is "10x". The coefficient is: 10.

Please help<br><br>4(4+2x)=x(x+5)

lapo4ka [179]

Answer:

EF = 6

Step-by-step explanation:

Using the secant- secant power theorem, that is

GF × GE = GH × GS

4(4 + 2x) = 5(5 + x) ← distribute both sides

16 + 8x = 25 + 5x ( subtract 5x from both sides )

16 + 3x = 25 ( subtract 16 from both sides )

3x = 9 ( divide both sides by 3 )

x = 3

Then

EF = 2x = 2 × 3 = 6

Ariana has a large piece of fabric that she wants to use to make some scarves. The number N of scarves she can make is inversely

AveGali [126]

Answer:

9 scarves.

Step-by-step explanation:

We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.

We know that equation of two inversely proportional quantities in in form $y=\frac{k}{x}$ , where, k is constant of variation and y is inversely proportional to x.

Let us find constant of variation using our given information.

$N=\frac{k}{A}$

$15=\frac{k}{3}$

$15*3=\frac{k}{3}*3$

$45=k$

Now, we will substitute $A=5\text{ and }k=45$ in our equation to solve for N.

$N=\frac{45}{5}$

$N=9$

Therefore, Ariana can make 9 scarves.
